Chapter 12: GigaStor in Financial Firms
Using Observer in financial firms
In an environment where even nanoseconds matter, a GigaStor allows you to
identify when an anomaly in your network occurs and alerts you to it so that you
can resolve it quickly.
If you are a network administrator in a financial or trading firm, small amounts
of time can mean the difference between making or losing money or making
money versus making a lot of money. Your networks must be fast, and your
trading algorithms must be running as efficiently as possible with no data loss on
your network. In addition to the in-depth network troubleshooting features, the
GigaStor has several components designed with your business in mind:
♦
GigaStor probe
: The GigaStor probe is a high-performance capture-based
network appliance that is extremely fault tolerant with redundant, high
efficiency cooling. It captures both packet and flow-based traffic for long-
term retention of raw, indexed data. Having this data allows you rapid
event analysis of errors and anomalies. It can sustain full-duplex wire
speed capture and write-to-disk.
♦
Trading Multicast analytics : Multicast is used in trading firms to deliver
information on pricing, volume, and more. Getting this information as
fast as possible is critical because it affects profits. Therefore, multicast
streams use connectionless UDP rather than the connection-oriented TCP
protocol to traverse the network. UDP has little overhead in comparison
to TCP (like the three-way handshake). Hence, it is much faster and more
efficient for traversing the network. However, UDP also has weaknesses
that can have seriously negative implications for the trading network.
Packets can be lost, arrive out of order, and/or be corrupted. Data is
not retransmitted when this occurs with UDP, and even if it were, given
the high speed of today’s trading, it would likely be too late. When any
of these occur, it directly impacts trade execution. No data can mean
